Former AC Milan youth coach Filippo Galli has spoken of working with Pierre-Emerick Aubameyang.
The Borussia Dortmund star came through the youth system at Milan.
"We could already see that he was very strong," Galli told Corriere dello Sport.
"He had a number of qualities, although in my Milan we tended to play 4-2-3-1, deploying him on the right of an offensive trident.
"Eventually he could have also played as a second striker. He was willing and eager to learn, Pierre read all the phases of the game very well.
"Along with [Matteo] Darmian, he was the best element in terms of understanding tactics in my team.
"We're talking about the Milan of Ancelotti, veteran of the Athens success against Liverpool in the Champions League. In attack there was an incredible amount of quality: [Pippo] Inzaghi , Kaka, Pato, [Alberto] Gilardino.
"You could see that he was a complete striker. He scored seven goals in five games played in Malaysia in the Champions League, a tournament reserved for only the major youth teams."
